The local picture in St Austell
Replacing a bungalow in PL25 and PL26 with two or more homes needs planning permission for the new homes, and Cornwall Council will look closely at the number of homes, their height, parking, bins and garden space for each household.
A replacement can sometimes fit better than squeezing a new home behind a bungalow that stays, because the whole plot can be laid out from scratch. Neighbours are consulted either way, and a design that respects single-storey homes next door usually meets fewer objections.
What happens next in St Austell
Tell us roughly where your St Austell bungalow is and how the plot is laid out. We check the title plan, the planning history nearby and the street from the desk, then talk through what you want from the land. If it looks viable, we visit, measure and sketch the options for you to consider, with no cost and no obligation at any point.
Free plot appraisal
We look at the plot’s width and depth, the access, the planning history nearby and the character of the street, then talk through what you want. It’s free, with no obligation, and a site visit follows if it looks viable.
Choose your route
You can sell a plot and stay put, sell subject to planning, grant an option, enter a joint venture, or keep the land and have us design, get planning for and build a new home on it.
Planning application
We prepare drawings and reports designed around single-storey neighbours and the street scene, usually seek pre-application advice, and submit. The council consults neighbours and makes the decision.
Sale or build
If you sell, your solicitor handles the transfer and any lender release. If we build, you receive a written quote after design and survey, and the new home is built and handed over to you.
Worth checking early
- Covenants on older estates can limit building, and resolving one takes time and may cost money.
- You’ll keep a smaller garden, and a drive alongside your bungalow brings cars past your windows.
- A two-storey home on a road of bungalows is often resisted, so designs may need to stay low.
Your questions, answered for St Austell
Can I sell part of my bungalow garden in St Austell and stay living there?
Yes. You keep the bungalow and sell the land behind or beside it, with or without planning, subject to survey, title and contract. If the bungalow is mortgaged, the lender must agree to release the plot. Take tax advice before you sell.
Will Cornwall Council allow a two-storey house next to bungalows in St Austell?
It depends on the street and the design. Councils are often cautious about two-storey homes among single-storey neighbours because of overlooking and the change to the street. Chalet designs with rooms in the roof are a common compromise, but the council decides.
How much garden does a bungalow in St Austell need to keep?
There’s no single figure. Councils look for enough private garden for both the existing home and the new one, and many have guidance on minimum garden sizes. We check your council’s guidance during the appraisal.
Could I build a home for a relative on my bungalow plot in St Austell?
Yes, through our design and build route. You keep the land, and we design, get planning for and build the new home. A separate home needs planning permission; an annexe used as part of the main house is treated differently.
